<kevino:tchncs.de> if someone correctly guesses the publickey image of my input in a transaction , can they infer anything from this publey image just from the on-chain data ?

<cookingnan:matrix.org> @kevino:tchncs.de: No. The key image is already public on chain. By itself, it only prevents double spending ie it doesn’t reveal which ring member is the real input, the amount, or the owner.

<kevino:tchncs.de> i mentioned "if the attacker knows my real input among decoys" then what

<kevino:tchncs.de> they public key image by itself won't reveal anything about the sender unless some valuable off-chain data is available for this transaction.

<cookingnan:matrix.org> @kevino:tchncs.de: If they already know which ring member is your real input, the key image itself reveals nothing extra. It only confirms that input was spent. They still can’t determine the amount, recipient, or change from the key image alone.

<kevino:tchncs.de> thanks , thats what i was confirming

<cookingnan:matrix.org> @kevino:tchncs.de: Np man , i appreciate your time looking at the product.

<kevino:tchncs.de> what product ?

<kevino:tchncs.de> i just asked a monero question.

<cookingnan:matrix.org> project i mean )

<kevino:tchncs.de> unless you created the project

<cookingnan:matrix.org> oh i thought you were asking about umbra lol

<cookingnan:matrix.org> 😅😅

<cookingnan:matrix.org> @kevino:tchncs.de: i did x.com/umbraXMR

tfw your likeness was used in an ad for closed source software without your permission

<kevino:tchncs.de> is there an option in a blockchain explorer to search by my output stealth address ?

<kevino:tchncs.de> like the same stealth address would also show up as an input in another transaction i did ?

<ofrnxmr> One-time addresses

<ofrnxmr> Looking to find when your decoy has been used? there is a tool for that

<kevino:tchncs.de> ok , so the same address won't appear as a input in another transaction ? not even as a ring member ?

<kevino:tchncs.de> @ofrnxmr: yup something like that

<ofrnxmr> github.com/pokkst/monero-decoy-scanner

<ofrnxmr> or was ^

<kevino:tchncs.de> but it should also match as input in my next transaction right ?

<ofrnxmr> github.com/nahuhh/monero-decoy-scanner

<ofrnxmr> oh, i have a fork. Idk if its outdated

<kevino:tchncs.de> i was trying to match them on explorer but it showing different key addresses

<kevino:tchncs.de> ok i'll check it out

<ofrnxmr> @kevino:tchncs.de: Of course. Key images cant be spent more than once

<kevino:tchncs.de> no i mean unspent outputs

<kevino:tchncs.de> i checked from the 16 decoys , none matched the address of my previous utxo stealth address

<rucknium> @kevino:tchncs.de: This software can do that. One of the creators is attending the MRL meeting today: monerovis.com

<rucknium> But the website could easily log your queries. You would get better privacy by self-hosting the explorer github.com/dnvie/MoneroVis

<kevino:tchncs.de> thanks rucknium !

<kevino:tchncs.de> yea i will self host it

<kevino:tchncs.de> well its slightly heavy to host it , requires additional 250gb storage and few days to build the db :(

<kevino:tchncs.de> understandable though

<ofrnxmr> im assuming it runa a node ..

<kevino:tchncs.de> yes it kinda builds like a whole custom db

<dnvie:matrix.org> Yes, it uses a custom database as the decoy data it needs is not directly extractable from the blockchain

<kevino:tchncs.de> will it be able to build the database using a pruned monero node ?

<dnvie:matrix.org> Haven’t tested it, but it should work

<jpk68:matrix.org> The easiest way is typically to first purchase another cryptocurrency (such as Bitcoin or Litecoin), and then swap it into Monero

<jpk68:matrix.org> Haveno/Eigenwallet/Trocador would all work for swapping

<yekco:matrix.org> @jpk68:matrix.org: thanks! that make sense, if i go the route og buying BTC or LTC first, whr would u recommend buying it? and for the swap, which of haveno, eigenwallet and trocador would u say is the most "beginner-friendly"?

<jpk68:matrix.org> A custodial exchange would be the easiest, while obviously not great for privacy

<jpk68:matrix.org> You could also see if there are any cryptocurrency ATMs near you, where you can purchase BTC/LTC with cash in-person

<jpk68:matrix.org> coinatmradar.com

<jpk68:matrix.org> Eigenwallet only works for swapping BTC -> XMR, but I'd say that's the easiest decentralized option

<yekco:matrix.org> thats really helpful, thanls again. it was what i had in mind, but is reassuring to hear it from someone else. if i could ask one more thing, what whold u recommend i be most careful about, or pay the most attention to?

<jpk68:matrix.org> Not sure I can think of anything, personally :|

<jpk68:matrix.org> But feel free to keep asking questions - #monero-support might be a better channel, though

<yekco:matrix.org> oh, thanks !

<yekco:matrix.org> thats really nice of you, thanks man!

<jpk68:matrix.org> No problem at all :)
